The effects of wind on the heat exchange between sand surface and atmosphere are examined by using a wind tunnel fixed sand column. The water vapor flux generated by the evaporation in the sand column subjected to the wind is expressed as the sum of the molecular diffusion flux and the mechanical dispersion flux. A change of the heat balance at the sand surface is caused by the wind velocity adjusted and is mainly affected by the sensible heat, the latent heat due to the evaporation and the soil heat conduction.
